Hello all,
I’ve been testing the use of RTKLIB/RTKPOST (all patches applied) for Static RTK, with or without GLONASS (I’m receiving signals from 6 to 8 GLO satellites). The hardware I’m using is exactly the same, both for rover and for reference. The baseline is 55 meters long. I’m collecting my observations at 20 Hz using 10-minute span RINEX files. For carrier frequencies I’ve been using L1+L2 and “fix-and-hold” ambiguities for GPS. After inspecting the positioning results I’ve got so far I’ve noticed that: 1. For GLO ambiguities, the same results are obtained either selecting “ON” or selecting “AUTO”. 2. Exactly the same results (up to the forth decimal!) are obtained regardless using GPS+GLONASS or GPS-only data. The behavior described in 1. can be easily explained by recalling that the GNSS hardware I’m using is the same, both for reference and for rover. However the behavior described in 2. keeps puzzling me and that’s the reason why I’m asking for your help. One small data file is available at https://dl.dropboxusercontent.com/u/7204666/DataSample.zip containing RINEX sample data and the positioning results I’ve got when using that RINEX data sample. Hope someone can help me. Best regards António
